A90/A91 Supra STG1 Fuel System Wiring Kit

$ 350.00

Single pump wiring kit designed to activate the secondary low pressure fuel pump (LPFP) in our A90/A91 Supra STG1 Fuel System Kit.

This LPFP activation harness integrates our STG1 Fuel System Upgrade with your port injection controller, allowing the controller to activate the second in-tank fuel pump. Compatible with the MOTIV ReFlex+ (auxiliary output) and the bootmod3 REV2 controller. For customers not running a controller, a Hobbs switch can be added to trigger the fuel pump relay based on boost pressure.

Unlike universal pump trigger harnesses, this kit is built vehicle specific with factory style connectors for a true plug and play installation. The Passthru Included option adds our fuel hat passthrough solution for clean, sealed wiring into the tank.

Extension Harness Option: The STG1 Fuel System harness runs into the passenger side footwell. The optional Fuel Pump Extension Harness extends the 2-pin DTM wiring so the harness can comfortably reach the engine bay, including driver side controller mounting locations. Select Single Pump for one fuel pump hardwire kit, or Dual Pump for two fuel pump hardwire kits sharing a single trigger.

Compatibility:
A90/A91 Toyota GR Supra (B58)

Proudly handmade in the USA with automotive-grade TXL XLPE insulated wire and assembled in an ISO 9001 Certified Facility.
